The parameters and the function of SynchroPulse are explained in more detail in the MIG/
MAG welding section.
F
Frequency - for SynchroPulse option
Unit Hz
Setting range OFF or 0.5 - 5
Factory setting OFF
NOTE! In order to activate SynchroPulse, you must (as a minimum) change the
value of the parameter F (frequency) from OFF to a value of between 0.5 Hz and
5 Hz.
dFd
delta Feeder - Welding power offset for the SynchroPulse option (defined by the wire feed
speed)
Unit m/min ipm
Setting range 0.0 - 2.0 0.0 - 78.74
Factory setting 2.0 78.74
AL.2
Arc length correction 2 (for the upper operating point of the pulsed welding power with the
SynchroPulse option)
Unit % (of welding voltage)
Setting range ± 30
Factory setting 0
NOTE! The arc length correction for the lower operating point is made using pa-
rameter AL.1.
ALS
Arc length start - Increased welding voltage as striking voltage at welding startup, for MIG/
MAG standard synergic welding. In conjunction with the Alt parameter explained below,
ALS makes an optimised ignition sequence possible.
Unit % (of welding voltage)
Setting range 0 - 100
Factory setting 0
Example
- ALS = 100 %
- Welding voltage currently set: 13 V
- Striking voltage: 13 V + 100 % = 26 V
ALt
Arc length time - Time for increased arc length via ALS. During time ALt there is a contin-
uous decrease in the arc length to the currently set value.
Unit s
Setting range 0 - 5
Factory setting 0
FAC
Reset power source to factory setting
Press and hold down the Store button for 2 s to restore the factory settings; when "PrG"
appears on the digital display, the power source has been reset
